Non-metallic Drum Pump
The portable, non-metallic Flex-I-Liner® rotary peristaltic pump from Vanton Pump and Equipment Corp. evacuates drums and totes containing acids, caustics, salts, chlorides and reagent grade chemicals, without corrosion of the pump or contamination of the fluid. The self-priming design has no seals to leak or valves to clog, and can run dry for extended periods without damage. Compact in size with integral handle, it fits on drum lids without protruding, and has sufficient lift characteristics to operate from the floor, skid or stand. Only two non-metallic parts contact fluid: a thermoplastic body block, and an elastomeric flexible liner that can be replaced in the field without special tools. The rigid body block is of solid polypropylene, UHMW polyethylene, or PTFE, and the molded flexible liner of natural rubber, Neoprene®, Buna-N®, Hypalon®, Viton®, or Nordel® elastomers, eliminating corrosion or contamination associated with metal pumps. The wide choice of thermoplastics and elastomers in which these pumps are available permits their use over the full pH range and for an extensive list of corrosive, volatile and viscous fluids.
